Addition to my first post: After reading BH's reply and re-reading your original post where other than the post subject title you did not specifically mention no brake lights to go along with no TL, BH may also have a correct approach.

IF you do not have normal brake lights and no TL then look into the brake switch area. If the brake lights function normally but not TL I would start by using a meter or test light just to make sure 12v is getting out of the brake switch on the light green wire and go from there. If brake switch is providing power out then look to the under dash TL on/off switch or the control and limit switch portion as well as the solenoids all located under the car.

If the 20 amp inline fuse located near the starter motor going to the solenoids and compensator motor is good then first check the limit switch. It is possible something there got bent or jammed and the switch arm cannot spring return so the limit switch is staying open preventing the down movement. Also check to see if something allowed the compensator to drive too far and the bars actually started to switch sides. In that instance, the system is confused and will want to do opposite to what is needed. Usually it blows the inline fuse if that happens but not always. Referring to the birds eye view, figure 21 in the suspension section of SM, make sure the short transverse bar on the drivers side goes to the front of the compensator, the long bar on the passenger side to the rear. If all that is good then it could be a control switch or solenoid failure. Note that if a solenoid failed, they are a special type and the typical starter solenoids found in parts stores will not work.
